Effect of the type of binder on physico-mechanical and thermal properties of mortars with a basis of coir

This paper aims to study the effect of type of binder on properties of mortars with coir. Two types of binders were used for the manufacturing of mortars containing coir: lime is used as binder for mortar n°1 (Mortar 1) and cement is used for mortar n°2 (Mortar 2). The measurements of the physical, mechanical and thermal properties of the specimens show that Mortar 1 has higher water absorption values than those of Mortar 2 and consequently has the lowest values of thermal conductivity. The results also indicate that dry density of the specimens has more important role than the type of binder on mechanical properties. Relationships were established between mechanical properties and dry density of these mortars. These relationships are independent to the type of binder. The mortars also satisfied most recommended thermal insulation standards. © 2006-2012 Asian Research Publishing Network (ARPN).
